Isa. 44:10 Who shapes a god and casts an idol, which can profit nothing? In this example, Isaiah was trying to destroy the peoples’ fear of pagan gods and their useless idols. The relative pronoun “which” modified the noun idol in the first line, so the second line explained something about the noun “idol.” Instead of repeating the same idea again in line two for the sake of emphasis, the prophet chose to add a new thought in line two about the uselessness of the idols in order to bolster his argument.
